Concept

In a figure series, track each changing feature independently, such as the numbers, their positions, and the symbol state.

The next figure must continue all of these patterns at the same time.

Application

  1. The first number stream is 1, 5, 9, 13. It increases by 4 and moves clockwise through top-left, top-right, bottom-right, and bottom-left.

  2. The second number stream is 3, 7, 11, 15. It also increases by 4 and moves clockwise through bottom-right, bottom-left, top-left, and top-right.

  3. The star alternates hollow, filled, hollow, so the next star must be filled.

Cross-check

The required figure therefore has 13 at the bottom-left, 15 at the top-right, and a filled star; this continues all three patterns.

Hence, the figure with 13 at the bottom-left, 15 at the top-right, and a filled star replaces the question mark.
